Abstract
PURPOSE: To prevent the internal surface of a steel pipe from sticking pulverized powder by a method wherein a projection or a projection unit operated by moving within the steel pipe in a longitudinal direcion, in which the air flow is developed to clean in the forwarding direction of the projection or the projection unit.
CONSTITUTION: A pipe end enclosure 1 is provided with the outlets 6, 7 at the front and the rear ends, which enables to move right and left by the wheel secured at the bottom. A separator 14 comprises a separating chamber 21 and a pipe and inserting section 18 provided with the partitions 19, 20 and the exhaust 22, the bottom of the separating chamber 21 being provided with a chute 23. The exhaust port 22 of the separator 14 is communicated with a dust collector, by suction operation thereof air current is developed to flow into the separating chamber by passing from the pipe end enclosure 1 to the internal steel pipe 9. Under this condition, the projection unit 4 is operated to project the grinding material into the steel pipe 9, moving the track 11 as retaining the steel pipe 9 to shift the projection unit 4 from the right end of the steel pipe 9 to the left.
